Passport including metallic fibers
View Patent ↗Various switchable RFID devices are disclosed. These switchable RFID devices may include one or more RFID tags and one or more switches. Some of these one or more switches are optionally wireless. In various embodiments, the switchable RFID devices include cellular phones, security devices, identity devices, financial devices, remote controls, and the like. The switchable RFID devices are optionally disposed in a passport. The passport may include radio frequency shielding.
1. A passport comprising:
an RFID tag configured to transmit identifying information;
a surface configured to visually display the identifying information; and
a cover comprising a first part and a second part separated by a fold, the first part and second part each including radio frequency shielding, the radio frequency shielding including metallic fibers and configured to shield the RFID tag when the cover is closed and configured to allow reading of the RFID tag when the cover is open.
2. The passport of claim 1 , wherein the radio frequency shielding is attached to the first part using an adhesive.
3. The passport of claim 1 , wherein the radio frequency shielding in the first part extends to within 5 mm of the fold.
4. The passport of claim 1 , wherein the shielding is laminated within the second part.
5. The passport of claim 1 , wherein the shielding is attached to a binding at the fold.
6. The passport of claim 1 , wherein at least a portion of the radio frequency shielding includes multiple layers of shielding.
7. The passport of claim 1 , wherein at the first part includes the RFID tag and the first part includes less of the radio frequency shielding than the second part.
8. The passport of claim 1 , wherein the radio frequency shielding includes a mesh.
9. A passport comprising:
an RFID tag configured to transmit identifying information;
a surface configured to visually display the identifying information; and
a cover including a first part and a second part separated by a fold, the first part including the RFID tag and the second part including a radio frequency shielding configured to shield the RFID tag when the cover is closed, and configured to allow reading of the RFID tag when the cover is open, the radio frequency shielding including multiple layers of metallic fibers laminated within the second part and at least part of the first part.
10. The passport of claim 9 , wherein the radio frequency shielding is configured to reduce radio frequency signals by more than 15 dB.
11. The passport of claim 9 , wherein the radio frequency shielding is attached to the first part using an adhesive and is attached to a binding at the fold.
12. The passport of claim 9 , wherein the radio frequency shielding in the second part extends to within 10 mm of the fold.
13. The passport of claim 9 , wherein the radio frequency shielding includes a mesh.
14. The passport of claim 9 , wherein the first part also includes the radio frequency shielding.
15. The passport of claim 14 , wherein the first part includes less of the radio frequency shielding than the second part.
